Can I use the Stripe Billing DESIGN.md with Cursor, Claude Code, or Codex?

Yes. Copy the DESIGN.md file into your project root and reference it in your agent rules. For Cursor, add it to .cursor/rules. For Claude Code, include it as CLAUDE.md. For Codex, add it to your system prompt. The agent will read it and apply the Stripe Billing visual system to any UI it generates.

What is a DESIGN.md file?

A DESIGN.md file is a Markdown document that describes a product's visual design system — color palettes, typography, spacing, and component patterns — in a format that AI coding agents like Cursor, Claude Code, and Codex can read and follow when generating UI.

How do I add the Stripe Billing DESIGN.md to my project?

Download or copy the DESIGN.md file from this page and place it in your project root. Then instruct your AI agent: "Read the DESIGN.md file in this project and follow its design system when generating UI." The agent will pick it up automatically in Cursor, Claude Code, Codex, and most modern AI coding tools.

Use with AI Coding Agents

Copy one of these prompts into your AI coding agent to apply the Stripe Billing design system to your project. The DESIGN.md file in your repo root is the source of truth.

# .cursor/rules (or DESIGN.md)
You are working in a project that uses the Stripe Billing design system.

Read the DESIGN.md file in this project root and follow it strictly when generating UI.
Match the brand's exact colors, typography, spacing scale, and border radius.
Do not create generic Tailwind UI — apply the visual language from DESIGN.md.

Key rules:
- Use the defined color palette, not arbitrary hex values
- Apply the correct font family and weight scale
- Follow spacing tokens (4/8/12/16/24/32px scale)
- Match component patterns: buttons, cards, inputs, badges as specified
